Patient-centered care (CCM)	The 20-item form of the PACIC-scale (The Patient Assessment of Chronic Illness Care; range: 1 = almost never, 5 = almost always, Cronbach’s alpha reliability α = 0.94). Example item: I was asked for my ideas when we made a treatment plan (Glasgow et al., 2005)
Trust	The 13-item scale measuring trust in health care personnel, (range: 1 = fully disagree, 5 = fully agree, α = 0.92).
